I don't think it is the case, no. The myth started well before

Ah okay, fair enough. Perhaps we just need those writing
guides/tutorials to emphasise that, when presenting examples of
execline-based service scripts, that such scripts don't _need_ to
be execline based. Because although these guides/tutorials might
not explicitly say "you need to learn execline", the fact that
people don't state up-front that execline is _not_ compulsory
might lead people to assume that it _is_.
In the case of documentation i'm putting together, i'm making an
explicit choice to have a shebang line with dash, because i don't
want people to feel they have to grok execline before they can use
s6 or s6-rc.
At any rate, i can only imagine your frustration at the longevity
of this 'furphy', to use an Australianism:
https://en.wiktionary.org/wiki/furphy#Noun
The point of hardcoding execline here is that I need a middle
ground
between "force up/down to be a path to an external script",
which is
not flexible wrt e.g. existing sysvinit/openrc scripts you way
want to
call with "start" and "stop" arguments, and "make up/down full
scripts/executable files", which requires embedding
scripts/executables
in the compiled db, which, no.
And that's *exactly* what execlineb is for.
The idea is for people to write
echo "/path/to/script start" > $oneshot/up
without wondering too much about it, and *without* needing to
get lost
in the details of execline syntax. But obviously, I suck at
predicting
user behaviour, and people always end up wanting to be too smart
and
tying their brains in knots about incredibly simple stuff, so,
whatever.
Heh. Well, i certainly wasn't trying to suggest that you'd made a
_bad_ or _problematic_ design choice! Just wondering if the design
choice had contributed to the "you must use execline" thing. But
if, as you say, this thing has long preceded s6-rc, then indeed,
the workings of s6-rc can't be a factor.
